  • Patent number: 10113616
    Abstract: A multi-speed transmission in planetary design for a vehicle having a transmission housing (10); a first shaft (1), the first shaft (1) being a drive (An); a second shaft (2), the second shaft (2) being an output (Ab); at least five planetary gear sets (RS1, RS2, RS3, RS4, RS5); at least seven additional shafts (3, 4, 5, 6, 7, 8, 9); and five shift elements (SE1, SE2, SE3, SE4, SE5).

  • Patent number: 9995385
    Abstract: A method and device for actuating a shift element of an automatic transmission having a start-stop function and a pressure medium pump driven by an internal combustion engine. The shifting elements are clutches or brakes that can be actuated by a piston which is actuated for engagement via pressure supplied to a pressure space. The pressure space is depressurized when the engine stops. To enhance start-stop operation, the shifting elements comprise an additional pressure space that acts, in opposition to the pressure space acting in the engaging direction, as a controllable restoring mechanism which can be rendered inactive, if desired. If the engine stops and the automatic start-stop function is activated, the additional pressure spaces, acting in the restoring direction, are depressurized before the pressure drop in the pressure spaces, acting in the engaging direction, of the pistons, but are otherwise permanently pressurized during driving operation.

In the first shifting position of the shut-off valve, the first pressure adjusting device is hydraulically connected to the respective shifting element cylinder through the shut-off valve. In the second shifting position of the shut-off valve, the shifting element cylinder is sealed by the shut-off valve relative to the first pressure adjusting device. The shut-off valve is an releasable check valve. The releasable check valve includes a check valve and an unblocking device. The unblocking device is actuatable by a control pressure from a second pressure adjusting device.
